And it says this on the rear fender:MOTORCYCLE NOISE EMISSION CONTROL INFORMATIONTHIS 1999 HONMY60650 MOTORCYCLE,P1, MEETS EPA NOISE EMISSION REQUIREMENTS OF 80dBA AT 3400RPM BY THE FEDERAL TEST PROCEDURE. MODIFICATIONS WHICH CAUSE THIS MOTORCYCLE TO EXCEED FEDERAL NOISE STANDARDS ARE PROHIBITED BY FEDERAL LAW. SEE OWNER'S MANUAL

This is an Oregon model, so California models are probably different. Hope this helps!
